Hello all. I keep my trees in my unheated garage during the winter. They seem to like it there. Is there a general rule for watering during the winter? Mainly how often? I have mixture of evergreen and deciduous trees. Any advice appreciated.
Hey Dave!Let them freeze solid and stay that way. I always mulched mine with wood chips on the floor and would place snow, when available, on the mulch. I never had to water in January or February, and usually not until late March.
I have a few out there that seem not to care...Most species can deal with frooze roots, up to few degrees of frost, as long as the above-ground parts do not get exposed to wind & sun. Only deep minus temperatures are a killer. My trees get frozen solid a few times each winter, but typically to no more than say 5-10 degrees of frost. If temperatures are expected to go lower for a serious amount fof time (longer than an occasional drop overnight) I try to give them some protection.

Temperate, cold hardy trees don't mind being in frozen soil at all. At 25 F, let's say, the water in the soil is frozen, but the water within the roots isn't. The goal is to keep the water within the roots from freezing. Some great articles can be found here...https://www.evergreengardenworks.com/overwint.htm, and here...https://www.evergreengardenworks.com/frzekill.htmHey Dave!
Just want to get your point of view on this...
I understand that many trees do well staying frozen over winter.
But isn't the whole thing about overwintering to keep the roots from experiencing a freeze, and having ice crystals piercing and cutting the roots??
Is this notion only true for "tender" trees?
